Title: Improvements in and connected with governing mechanism for internal combustion engines
IPC: F02D17/00
Filed: 1919-11-20
Abstract: 159,023. Norris, H. Kent-, and Plenty & Son, Ltd. Nov. 20, 1919. Regulating.-In an inertia governor adapted to cut off the fuel feed when excessive speed occurs, means are provided for ensuring that an injection of fuel less than normal occurs immediately after a cut-out operation, in order to avoid the violent explosion which usually occurs after a cutout period. A reciprocating rod a is formed with a projection b arranged to slide over an incline d, so that when excessive speed occurs, the rod is thrown outwards sufficiently to engage a lever f, which is thereby rotated and actuates an arm g and cam j so as to operate a valve k controlling the fuel supply. For example, the cam may open a by-pass valve, or may hold open a suction valve, of the feed-pump. The cam is then locked in the operative position by a pawl l engaging a notch m in the cam, an extension l<1> of the pawl falling into the path of the rod a so as to be actuated thereby to release the cam at the end of the next up-stroke of the rod a, the cam being then returned by a spring. The arm l<1> is fitted with a screw stud p which is adjusted so that the rod a contacts therewith towards the end of the stroke of the feed-pump, thereby ensuring the smaller supply of fuel immediately after the cut-out. A step-by-step arrangement may be provided between the cam and pawl, so that the return to normal fuel feed occurs in successive stages during two or more upward strokes of the rod a. In an engine with two or more cylinders, similar cams are provided on each cylinder, operating-plungers being provided between the arms g of the cams. In a modification, the cams are replaced by lever arms.

Patent GB-483715-A (GB)
Title: Improvements in or relating to guards for presses, punches and like machines
IPC: F16P3/04
Filed: 1936-10-23
Abstract: 483,715. Machinery guards. SCHULER AKT.-GES., L. Oct. 23, 1936, No. 28910. Convention date, Oct. 23, 1935. [Class 80 (iv)] When a plate 9 on a rod 5 at the side of the table 1 of a press or the like is depressed against the action of a spring 10 it turns a latch 11 away from a lug 12 on the frame of a guard 14 so that the latter can rise to guarding position under the influence of a spring 36, Fig. 5. The spring tends to pull down a rod 32 pivoted to an arm 29 on a shaft 28 on which is also fast an arm 23 carrying a roller 25 running in a groove in an arm 21 on a spindle 20. A rod 15 connects the guard with the spindle 20. When the latch is released, therefore, the downward pressure of the roller in its groove turns the spindle 20 in a clockwise direction and raises the guard. Descent of the rod 32, after lost motion due to a slot 38 has been taken up, turns the shaft 41 to engage the clutch. When the guard is fully raised the roller 25 is at the end of the groove and locks the guard. The machine now operates and the power shaft 41 and cam 42, Fig. 4, rotate. The stamping operation concluded, the follower 43 and rods 44 45 and 34 are raised, and, after the lost motion entailed by a slot 33 has been taken up, the shaft 28 is turned clockwise so that the roller 25 moves back along its groove and the guard is positively brought back to the open position shown in Fig. 2 and finally held by the latch 11. Thus the only action required of the operative is the light one of depressing the plate 9, which is located preferably in a cutaway portion of the feed table 3.

Title: Processes for preparing tetrazoles
IPC: C07D487/04
Filed: 1927-11-01
Abstract: 280,529. Boehringer, A., (trading as Boehringer Sohn, C. H.). Nov. 10. 1926, [Convention date]. Samples furnished. Tetrazoles are produced by the action of azides or free hydrazoic acid on esters of oximes, e.g. oximes of cyclic ketones, and particularly the sulphonic esters, or the so-called Beckmann transformation products of these esters. The reaction takes place in presence of water or organic solvents, in neutral or slightly acid solution, or in presence of basic substances of organic or inorganic nature, but in the absence of concentrated mineral acid. The azide and oxime esters are employed in equi-molecular quantities or with the former in slight excess. An example is given of the preparation of 1 : 5-pentamethylenetetrazole together with some #-leucine lactam from cyclohexanoneoxime in caustic soda, benzenesulphochloride, and sodium azide; the tetrazole derivative can be separated from the leucine lactam bv distillation or by precipitation with mercuric chloride solution. The Specification as open to inspection under Sect. 91 (3) (a) states that, instead of the esters, the components necessary for ester formation may be used. It also includes examples according to which the following derivatives of 1 : 2 : 3 : 4-tetrazole are produced :-(1) 1 : 5-dimethyl-1 : 2 : 3 : 4-tetrazole from the benezenesulphonic ester of acetoxime and sodium azide; (2) 1-benzyl-5-methyltetrazole from the p-toluenesulphonic ester of benzylmethylketoxime and sodium azide; (3) 1 : 5-diphenyltetrazol from benzophenone-oxime by esterifying with aqueousalcoholic caustic soda and benzenesulphochloride, adding sodium azide, and warming; or by treating a mixture of benzophenone-oxime and hydrazoic acid in chloroform with thionyl chloride; (4) 1 : 5-pentamethylenetetrazole from cyclohexanone oxime and (a) benzenesulphochloride, pyridine or caustic soda, and chloroform followed by sodium, potassium, or ammonium azide, (b) hydrazoic acid in benzene, benzenesulphochloride, and sodium azide, (c) pyridine, phosphorus oxychloride, and sodium azide.
